COP-WIN DING MACHINE.

Application filed April 8, 1927, Serial No.

This invention relates to a cop winding machine of the kind wherein thethread guide is reciprocated by a cam-supported traverse bar andadvanced on the latter by 5 means of a progress wheel operated bycontact with the cop at the end of the traverse, and the inventionconsists in the provision of means whereby additional reciprocatingmovement is imparted to the thread guide independently of the traversemechanism and within shorter limits in order to lay the yarn in short,open, overlapping spirals on the conical nose of the cop. The additionalreciprocating movement may be obtained'either byconnecting the threadguide to a crank element on the progress wheel device, or by adaptingthe traverse bar for independent movement relative to the trav- .Fig. 1of the accompanying drawings represents a side view' of the mechanism,

The machine has a driving shaft 1 which operates a cam shaft 9 by meansof a pinion 6 and a gear wheel 7. For each winding mechanism the shaft 1carries a friction wheel 2 which supports and drives a wind- 'ingspindle 4 through the medium of a The yarn 41 is led from a swift 37 orfrom a spool 38 tothe thread guide 34 whereby] it is laid on the conicalnose of the cop 5.

The thread guide is reciprocated by the cams 10 and the rail 12 alongthe whole extent a (Fig. 5) of the nose, and it is advanced relativetothe traverse bar 14 by the friction progress wheel 13 which for thispurpose contacts with thebody of the co at the end of-the traverse.

lhe mechanism and action so far described is well-known. According tothe invention means are provided for, reciproeating the thread guideindependently of the traverse rail 12 a plurality of times during eachtraverse so as to lay the yarn on the nose in short, open, overlappingspirals. The mechanism-employed for this purpose may be constructed indifi'e rent ways. Ac-

cording to Figs. 1 to 6 the driving shaft 1' carries a cam 15 whichrocks the lever arm 21 through the medium of a roller 16. The

- arm is' pivoted at 18 to a bracket 20 on the table 19 and iscontrolled by a spring 22 which holds theroller 16 against the cam.

A rod 23 connects the lever arm 21 with an arm 25 connected to a shaft24,.and a link 29 connects the arm 25 with an arm 25' connected to ashaft 24'. Thetwo shafts 24 and 24' are mounted one-above the other infbrackets 28 surmounting the table 19. For

each winding mechanism there is an upright shackle 31 which is pivotallyheld by two arms 26 and 26 mounted on the two shafts 24 and 24 one oneach. The rocking movements imparted by the cam 15 and the lever 21 tothe shafts 24, 24 causes the shackle 31 to be reciprocated horizontallyin a plane at right angles to the traverse rail 12. The thread guide eye34 is formed on a crank element which is rockingly mounted in an arm36'of an angle piece carried by the friction progress wheel 33. One armof this crank element holds the eye 34, another arm 33 of the same beingformed with a hook 32 which remains in engagement with the shackle 31 inall positions of the thread guide. The arms 35 and 33 are soarrangedrelative to each other that the movements of the shackle 31 causes thethread guide eye 34 to reciprocate in the direction of the arrow b(Fig. 1) and lay the yarn in short, open spirals on the nose of the cop.The stroke 0 (Fig. 5) of the guide and thus the angle a of the spiralcoils may be varied by connecting the rod 23 to different points on thelever arm 21, the latter being provided with a plurality of apertures 17for this purpose.-

The angle piece which carries the thread uide element 1s shown on alarger scale in ig. 6. It has a forked arm whereby it is guided on anupright rod 39. The latter allows the angle'piece to follow the up anddown movements of the wheel 13 but prevents it from rotating togetherwith the same.

In order to obviate excessive accumulation of mechanisms on the machinetable, the device may be modified, for instance as shown in Figs. 7 to11. In this case the crank element 35, 33 which imparts the additionalreciprocation to the thread guide 34 is held in an angle piece 36' andoperated by a shackle 31' which is firmly secured to an lipright rod 39.The latter, which takes the place of the guide rod 39 of the previousconstruction, is formed with a downward I extension 70 whereby it isrotatably held in a boss ,71 secured to the traverse rail'12. A plate 72on the rail holds the boss and. also the traverse bar 14. A bracket 73which is secured to the boss 71, carries a bearing 74 for the lower endof the rod extension 70. Between the boss 71 and the bearing 74, the rodextension 70 carries a vane 56 which cooperates with an eccentric or cammounted on a shaft 54 arranged under the machine table. The shaft 54,which has an eccentric I for each winding mechanism, receives rotationfrom the shaft 1 through the medium of a round belt 52 and groovedpulleys 51 and 53. Anarm 73' on the bracket 73 and an arm 56' on thevane 56, are connected by a spring 75 which maintains the vane in con-.

' tact with the eccentric 55, the vane being therefore oscillated in thedirection of the arrow f (Fig. 11). The oscillations of detrimentallyaffected by the angular movement of the thread guide, the device may bemodified with a view to render the thread guide movement parallel withthe winding spindle. For this purpose the arrangement shown in Figs. 12to 17 may be resorted to. In this arrangement the shaft 54 and the vanes56 are retained, but the latter are rotatably mounted on reduced ends 57on bolts 58 which depend from the traverse rail 12. Connected to thevane 56 is a bifurcated arm 60 in the .gap 59 of which one arm 35 01? abell-crank is engaged. The bell-crank is pivoted at 61 to a bracket 62depending from the traverse rail 12. The other arm 33 of thebell-crankis bifurcated and provided with slots 63,for engagement withpins 64' atopposite sides of the traverse bar 14 which in this case isprolonged through the rail 12 parted to the'bell-crank 35, 33 which inits turn rcciprocates the traverse bar 14 in longitudinal direction. Thethread guide 34 is in this case held stationary relative to the frictionwheel 13 in the usual manner.
